feat(ACTIVITY-WP-0029): inventory callers, retarget sweep, bound execution

Map every State Hub/core-hub caller to a post-retirement owner. Keep the
15-minute sweep schedule here and point the engine at repo-manager
(State Hub dual-run by default, REPO_MANAGER_URL when present). Publish
GET /execution/semantics and 410 workplan launch routes so State Hub
/execution/* is not re-homed as a task database. T03 still waits on
HUB-WP-0004.

# Execution queue boundary
Replaces State Hub `/execution/*` as the place callers look for *when work
should fire*. It does **not** move workplan files, task lifecycle, or ITC
Task Model types into activity-core.
## What activity-core owns
| Surface | Meaning |
| --- | --- |
| Temporal Schedule + `POST /activity-definitions/{id}/trigger` | When an ActivityDefinition fires |
| `POST /ops-runs/claim` and complete/fail/heartbeat | Claimable **ops run** for that fire (ACT-ADR-005) |
| `GET /execution/semantics` | This contract |
`port.schedule` (hub-extension 0.1) is the hub-core **outbound** port that
asks activity-core to wake a schedule or accept a launch of an
ActivityDefinition. activity-core implements the receiving side.
## What activity-core does not own
| Concern | Owner |
| --- | --- |
| Workplan / task **files** and their status | The repo (ADR-001) |
| Work-record **index** and C-rule consistency | repo-manager (`port.work`) |
| Task / Commitment / TaskState vocabulary | info-tech-canon Task Model |
| Assign / track / close a development task | issue-core / work records |
| Policy publication | policy-nexus |
| Workplan `execution_state` rows on State Hub | retiring; do not re-home as hub tables here |
A workplan being `active` is a **lifecycle** fact in the repo file. An
ops_run being `open` is an **automation fire**. Those are different planes
(ACT-ADR-005). Mapping State Hub `POST /execution/launch-requests` onto
“create a workplan execution row here” would collapse them again.
## Replacement for State Hub routes
| State Hub route | Replacement |
| --- | --- |
| `GET /execution/semantics` | `GET /execution/semantics` on activity-core (this contract) |
| `POST /execution/launch-requests` (workplan) | Do not send here. Queue the workplan in the **repo file**; use an ActivityDefinition + ops_run if the work is a recurring/ops fire |
| `GET /execution/launch-requests` | `GET /ops-runs` |
| `GET /execution/workplan-stack` | repo-manager work index / hub-core projection — not this API |
| `PATCH /execution/workplans/{id}/intent` | Edit the workplan file; repo-manager indexes it |
Callers that still hit `/execution/*` on activity-core for workplan ids get
**410** with `replacement_ref` pointing at the table above.
## Semantics payload
`GET /execution/semantics` returns:
- `activity_core_owns` — schedules, triggers, ops_run claim/complete
- `activity_core_does_not_own` — workplan files, task lifecycle, C-rules
- `replacements` — map from retired State Hub paths to current surfaces
- `port``port.schedule` (consume; do not invent the hub-core side here)

# State Hub / hub-core caller map
Inventory for ACTIVITY-WP-0029-T01. Current URLs still go to State Hub unless
noted. **Target owner** is who should own the *capability* after retirement.
activity-core stays the scheduler even when it is not the engine.
Hub-core port names are from `helixforge.hub-extension` 0.1
(`prj-state-hub-retirement/architecture/hub-extension-contract_v0.1.yaml`).
HUB-WP-0004 has not shipped those ports yet.

## Sweep split (T02)
- **Schedule:** activity-core cron `*/15 * * * *` UTC (`state-hub-consistency-sweep`).
- **Engine:** repo-manager C-rules / `rmgr reconcile`.
- **Adapter until RM HTTP exists:** State Hub `POST /consistency/sweep/remote-all`
(dual-run when `RM_RECONCILE` is on). Override with `CONSISTENCY_SWEEP_URL`
or `REPO_MANAGER_URL` + optional `CONSISTENCY_SWEEP_PATH`.
## Evidence sink (T03 — wait)
All `POST /progress/` callers stay on the State Hub beachhead until
**HUB-WP-0004** publishes `port.events.progress` / `port.events.interaction`.
Do not add a second permanent progress host.
## Execution (T04)
State Hub `/execution/*` is **not** a task database and must not move here as
workplan rows. See `docs/execution-queue-boundary.md`.
